I had my own rainbow machine for years then last month I had a call telling me that one of my friends wants to do a cleaning service for me i told the person that I already have a machine that does the same thing then she told me that they also accept trade in of old rainbow machines. then 2 weeks ago they came to my house to do a cleaning service then offered me to trade in my old machine to lura their product. now i'm using lura same quality just less bulky to keep.
